The Age of Kings is dead . . . and I have killed it.

It's a bloody business overthrowing a king...
Field Marshal Tamas' coup against his king sent corrupt aristocrats to the guillotine and brought bread to the starving. But it also provoked war with the Nine Nations, internal attacks by royalist fanatics, and the greedy to scramble for money and power by Tamas's supposed allies: the Church, workers unions, and mercenary forces.

Stretched to his limit, Tamas is relying heavily on his few remaining powder mages, including the embittered Taniel, a brilliant marksman who also happens to be his estranged son, and Adamat, a retired police inspector whose loyalty is being tested by blackmail.

In a rich, distinctive world that mixes magic with technology, who could stand against mages that control gunpowder and bullets? PROMISE OF BLOOD is the start of a new epic fantasy series from Brian McClellan.
